Take over us to accomplish what? Who would manufacture them and program them? Robots gain nothing.

well the thing with robots is they have no morals. so lets say you program a robot to go to the other side of a city the most time efficient way possible but the most efficient way involves a little kid or puppy or something and since the robot has no morals he just runs right over the kid/puppy to get to the destination. robots will probably have nothing to gain from killing us but they also have nothing to lose.

I don't believe sentience and consciousness can be produced from a machine. They can't be made self aware. They only know and do what you tell them to. They don't think for themselves. Consciousness is not an epiphenomena of matter. Consciousness is primary and matter is secondary.

When we build robots that can design and build better robots and when we design computers to build better and exponentially faster computers then man will no long be "in the loop". It's a bit like the movie "A.I." where at the end of the movie robots had evolved to perhaps the limits of technology and resembled alien lifeforms more than machines. Of course that as science fiction and robots are a long way from that. Also it may be that it is not possible for true A.I., where a machine becomes self-aware. But should that happen all bets are off.

If we program robots for maximum efficiency, and within that program is an algorithm that enables the robot to "learn" how to become more efficient, maybe that could be a danger. This programmed "desire" for efficiency I think could be considered a type of independent robot intelligence. We could program robot morality too, that over rides everything else. But...I just don't trust robots.

Watch the movie, "Colossus - The Forbin Project" on Youtube for an example of this.

The acceptance of authority does not lead to intelligence.
A mind untouched by thought...the end of knowledge.
To see reality loose your opinions.

I have a robot car it obey's my every command,and I put it to sleep every night in its own garage.If I forget to wear my seat belt it tells me.If I dont close a door properly it tells me. if a tyre needs more pressure ,it tells me and so on,what more could you ask for ?.
